When a stroke affects an extensive portion of the front and back regions of the left hemisphere, the result may be global aphasia. Survivors with global aphasia: May have great difficulty in understanding words and sentences. May have great difficulty in forming words and sentences. May understand some words. Get out a few words at a time. Have severe difficulties that prevent them from effectively communicating.
Haemorrhoids is one of the most common problems seen in surgical OPD. Open haemorrhoidectomy has remained the gold standard for a long time with a high post-operative morbidity. The quest for a better understanding of the pathology of haemorrhoids resulted in the evolvement of stapler haemorrhoidopexy. Our aim is to study the efficacy of stapler haemorrhoidopexy with regards to role of immediate post-operative morbidity. A prospective study of 50 patients (n = 50) with the second- and third-degree symptomatic haemorrhoids was done. The mean age of the patients was 44.1 years. Fourteen patients had co-morbid conditions. The average duration of the operation was 29 min. Patients with the second-degree haemorrhoids had higher rate of complication. The complication rate was 32%. Three patients had urinary retention. Two patients had minor bleeding, and one patient experienced transient discharge. The mean analgesic requirement was 2.4 tramadol, 50 mg injections. Ten patients had significant post-operative pain. Average length of hospital stay was 2.7 days. There were no symptomatic recurrences till date.
Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve). As a result, air accumulates and compresses the lung, eventually shifting the mediastinum, compressing the contralateral lung, and increasing intrathoracic pressure enough to decrease venous return to the heart, causing shock. These effects can develop rapidly, particularly in patients undergoing positive pressure ventilation.
Therapeutic anticoagulation is recommended for all women with acute VTE; prophylactic anticoagulation is recommended for women at risk, such as those with a past history of thrombosis or thrombophilia or with a mechanical heart valve. The preferred anticoagulants during pregnancy are the heparin compounds.
Eosinophilic granulomatosis with polyangiitis (EGPA)—or, as it was traditionally termed, Churg-Strauss syndrome—is a rare systemic necrotizing vasculitis that affects small-to-medium-sized vessels and is associated with severe asthma and blood and tissue eosinophilia. [1] Like granulomatosis with polyangiitis (Wegener granulomatosis), and the microscopic form of periarteritis (ie, microscopic polyangiitis), EGPA is an antineutrophil cytoplasmic antibody (ANCA)–associated vasculitide. [2, 3, 4, 5] In 1951, Churg and Strauss first described the syndrome in 13 patients who had asthma, eosinophilia, granulomatous inflammation, necrotizing systemic vasculitis, and necrotizing glomerulonephritis. [3] In 1990, the American College of Rheumatology (ACR) proposed the following six criteria for the diagnosis of Churg-Strauss syndrome [6] : Asthma (wheezing, expiratory rhonchi) Eosinophilia of more than 10% in peripheral blood Paranasal sinusitis Pulmonary infiltrates (may be transient) Histological proof of vasculitis with extravascular eosinophils Mononeuritis multiplex or polyneuropathy
Compartment syndrome can develop in the foot following crush injury or closed fracture. Following some critical threshold of bleeding and/or swelling into the fixed space compartments, arterial pulse pressure is insufficient to overcome the osmotic tissue pressure gradient, leading to cell death. The complicating factor is related to the magnitude of the force of the crush injury. The amount of swelling or bleeding has to be sufficient to impair arterial inflow, while not being of sufficient magnitude to produce an open injury, which decompresses the pressure within the affected compartments. When the injury is open, we then attribute the late disability primarily to the crushing injury to the involved muscles.
Boxer’s Knuckle is an injury to the structures around the first knuckle of a finger, also known as the metacarpophalangeal joint (MPJ). The skin, extensor tendon, ligaments, joint cartilage, and the bone of the metacarpal head may all be involved. Repeated impacts to the extensor tendon over the knuckle causes Hypertrophic Interstitial Tendonosis, or HIT Syndrome. This is a thickening, weakening, inflammation, and scarring of the extensor tendon.
A rotator cuff tear is a common injury, especially in sports like baseball or tennis, or in jobs like painting or cleaning windows. It usually happens over time from normal wear and tear, or if you repeat the same arm motion over and over. But it also can happen suddenly if you fall on your arm or lift something heavy. Your rotator cuff is a group of four muscles and tendons that stabilize your shoulder joint and let you lift and rotate your arms. There are two kinds of rotator cuff tears. A partial tear is when the tendon that protects the top of your shoulder is frayed or damaged. The other is a complete tear. That’s one that goes all the way through the tendon or pulls the tendon off the bone.
A leaking mitral valve allows blood to flow in two directions during the contraction. Some blood flows from the ventricle through the aortic valve – as it should – and some blood flows back into the atrium. A leaking (or regurgitant) aortic valve allows blood to flow in two directions. Oxygen-rich blood either flows out through the aorta to the body – as it should – or it flows backwards from the aorta into the left ventricle when the ventricle relaxes. Leaking valves can cause the heart to work harder to pump the same amount of blood.
Start out with a visit to a doctor called a urologist. He'll give you a physical exam and ask you questions about your lifestyle and medical history, such as: Surgeries you've had Medications you take Your exercise habits Whether you smoke or take recreational drugs He may also have a frank discussion with you about your sex life, including any problems you've had or whether you have or ever had any STDs (sexually transmitted diseases). You'll probably be asked to give a sample of semen for analysis.
www.lung.org > Lung Health and Diseases > Lung Disease Lookup > Silicosis Learn About Silicosis Silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. It mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. Over time, exposure to silica particles causes scarring in the lungs, which can harm your ability to breathe. Key Facts There are three types of silicosis: acute, chronic, and accelerated. It occurs in workers from mines, foundries, sandblasting, and glass manufacturing. About 2 million US workers remain potentially exposed to occupational silica. There is no cure for silicosis, but it can be prevented. What Is Silicosis? There are three types of silicosis: Acute silicosis, which causes cough, weight loss, and fatigue within a few weeks or years of exposure to inhaled silica. Chronic silicosis, which appears 10 to 30 years after exposure and can affect upper lungs and sometimes cause extensive scarring. Accelerated silicosis, which occurs within 10 years of high-level exposure. Silicosis can develop within a few weeks to even decades after exposure. When people breathe silica dust, they inhale tiny particles of the mineral silica. This silica dust can cause fluid buildup and scar tissue in the lungs that cuts down your ability to breathe. This can lead to lung scarring and cough, weight loss, and fatigue.
In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The cerebral cortex and a number of brainstem nuclei exert influence over the sensory input of the muscle spindles by means of the gamma motoneurons that are located in the anterior horn; these neurons supply a set of muscle fibers that control the length of the muscle spindle itself.
